TECHNOLOGY

SkyVision combines the communication industry’s most advanced technologies with the in-depth knowledge of experienced professionals. This allows us to provide customers with highly optimized satellite and fiber networks that guarantee both cost-effectiveness and the most reliable connectivity.

 

 

 

 

Some of the technologies SkyVision employs include:

 

VSAT
Very Small Aperture Terminal (VSAT) is a small earth station used for broadcast, reception and interactive communications via geosynchronous satellites. Typical VSAT antenna diameter sizes are between 1.8 to 2.4 meters and utilize Ku-Band and C-Band for satellite transmission.
SkyVision services employing VSAT include:

DVB
Digital Video Broadcasting is a suite of internationally accepted open standards for digital television. Digital Video Broadcast – Satellite (DVB-S) defines the encoding format for multiple video channels on a single QPSK satellite carrier. DVB-S2 is a next-generation advanced version of DVB-S that offers more capacity and stronger forward error correction at low signal levels.


SkyVision services employing DVB include:

 

 

SCPC
Single channel per carrier (SCPC) refers to using a single signal at a given frequency and bandwidth. Most often, this is used on broadcast satellites to indicate that radio stations are not multiplexed as subcarriers onto a single video carrier, but instead independently share a transponder. It may also be used on other communications satellites, or occasionally on non-satellite transmissions.


SkyVision services employing SCPC include:

 

 

 

Geostationary Satellites
A geostationary satellite is a satellite revolving approximately 22,000 (36,000 km) miles above the earth’s surface in the plane of the equator, with an orbital period equal to one sidereal day. Satellites positioned in a GEO orbit appear to an observer on the surface of the earth as stationary objects in the sky. All SkyVision services employ geostationary satellites.

Inclined Orbit Satellites
A satellite in an inclined orbit is the same as a satellite in a geostationary orbit, with one important difference: Once a satellite has been placed into a geostationary orbit it gradually starts to drift into a figure-eight orbit, due to the gravitational influence of the sun and moon. Keeping a satellite in its geostationary orbit (in order to maintain contact with a fixed antenna) requires activating thrusters powered by large supplies of rocket fuel, activated in bursts every few weeks. Inclined-orbit technology employs a motorized antenna technology to track (i.e. maintain contact with) the satellite’s natural figure-eight orbit. Allowing the satellite to oscillate with the natural gravitational pull dramatically saves on fuel, thus both extending the satellite lifespan and reducing its operational costs.


SkyVision offers a DVB/SCPC service over Inclined Orbit.

MPLS
Multiprotocol Label Switching integrates Layer 2 information about network links (bandwidth, latency, utilization) into Layer 3 (IP) within a particular autonomous system – or ISP – in order to simplify and improve IP-packet exchange. MPLS gives network operators a great deal of flexibility to divert and route traffic around link failures, congestion, and bottlenecks.
